Climate experts expect to see activity for a couple more months and there are several reasons why.

They say because of global warming and higher water temperatures farther north, along with signs of El Niño, hurricanes are now following a new and more menacing route.

"In other words, the major hurricane track, currently, is basically confined to the south of the Hawaiian Islands. But with the global warming, this track may be projected to shift northward," or closer to Hawaii, said Pao-Shin Chu, state climatologist and University of Hawaii meteorology professor.

Meanwhile, forecasters say Hurricane Olivia is in a low wind shear environment — and that's not a good thing.

"Right now, Olivia is tracking westward, south of the ridge," said John Bravender, warning coordination meteorologist at the Central Pacific Hurricane Center. "We're not expecting Olivia to make that same sort of turn that we saw with Miriam or we saw with Norman, and be more of a threat to us."

Extended models show activity tapering off a bit but only temporarily.

Scientists expect a busy hurricane season through the end of November.

Behind Olivia, there is even more activity brewing. If it were to develop, it would be named Paul.
